WebHere we demonstrate that a homology-mediated end-joining (HMEJ)-based method can be used to create gene-edited cattle that displays precise integration of a functional gene at the ROSA26 locus. We found that the HMEJ-based method increased the knock-in efficiency of reporter genes by eightfold relative to the traditional HDR-based method in … WebIn mathematics, homology [1] is a general way of associating a sequence of algebraic objects, such as abelian groups or modules, with other mathematical objects such as topological spaces. Homology groups were originally defined in algebraic topology. Similar constructions are available in a wide variety of other contexts, such as abstract ...

Mouse B cells deficient in the core NHEJ factors, Ku, XRCC4, and ligase IV, displayed ∼50% reduced CSR compared to controls (Boboila et al., 2010a,b; Soulas-Sprauel et al., 2007a; Yan et al., 2007; Han and Yu, 2008 ).

WebNon-homologous end joining (NHEJ) is an endogenous DNA repair mechanism that is induced by the creation of double stranded breaks (DSBs) in the genome. It is referred to as “non-homologous” repair because the two broken “ends” of the DNA are indiscriminately rejoined (ligated) back together with minimal reference to DNA sequence. WebThe chain groups are. C 0 ( T 2) = { k e 0 k ∈ Z } = Z. C 1 ( T 2) = { k 1 e a 1 + k 2 e b 1 k 1, k 2 ∈ Z } = Z ⊕ Z. C 2 ( T 2) = Z. C k ( T 2) = { 0 }, k > 2. Now the homology groups: …
